whats happening?

so im usually all bubbly, hiper and loud around m y friends, but when i'm in a group with other people i don't know that well my personality changes i turn serious-ish , but its only with certain people, like in class i didn't know the ppl in my group but i wasn't shy talking to them, but around these other people, was it because they're also very loud, and i feel out of place?

I know exactly how you feel! I'm the same way. here's what i usually do, it might work for you, too: 1. be yourself no matter what, 2. If ithe people you're hangin' with aren't your best buds, chances are you'll still have something in common with them, so be nice and just try to find common ground.
